Not that Easy - Not Worth the Effort

Terrible experience. Please reconsider before you buy.
I bought 4 lowers: ruined two and the other two are very substandard. I would not recommend milling out your own lower. The finished product is very rough and, for all the effort, just not worth it. Buy a completed lower and save the money, time and grief.
Even though I bought an Easy Gig Gen 1, it took 1 hour to set up, 4 hours to mill out one lower, and 2 hours to clean up. It's a messy, dirty process. I'm still finding aluminum shavings in my garage and clothing two weeks later.
I read the instructions twice and watched 7 or 8 YouTube videos before I started. Yes, I used a quality drill press, a commercial grade router and I am handy with tools etc. A novice, however, wouldn't stand a chance producing a serviceable lower on the first try. Maybe that's why they sell 3-packs
